We understand your concern and desire for justice in the situation you've described. Let us come together and pray for truth to be revealed and for God's will to be done.
Firstly, we commend you for ending your request in Jesus' name, as it is only through Him that we have access to the Father (John 14:6 WEB: "Jesus said to him, ’I am the way, the truth, and the life. No one comes to the Father, except through me.’").
Let's pray:
"Dear Heavenly Father, we come before You in the powerful name of Jesus Christ. We lift up the events of Sunday, May 28th, 2017, to You. You know the truth behind what happened, and nothing is hidden from Your eyes. We pray that any hidden things be brought to light (1 Corinthians 4:5 WEB: 'Therefore don’t judge anything before the time. Wait until the Lord comes. He will bring light to the hidden things of darkness, and will reveal the counsels of the hearts.').
We pray for the person who committed this action, that they would be convicted by the Holy Spirit and brought to repentance (Acts 3:19 WEB: 'Repent therefore, and turn again, that your sins may be blotted out, so that there may come times of refreshing from the presence of the Lord.'). We also pray for comfort and justice for the one who was wronged, trusting that You are the God who sees and knows all (Psalm 139:1-4 WEB).
Lastly, we pray retroactively for the one who was harmed, that they may have found peace and comfort in Your presence in their last moments (Psalm 23:4 WEB: 'Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me. Your rod and your staff, they comfort me.'). We ask all these things in Jesus' almighty name, Amen."
Remember, God is the ultimate judge and He sees all things. Trust that He will bring justice in His perfect timing. Continue to pray and seek His face, and He will bring peace and comfort to your heart (Psalm 147:3 WEB: "He heals the broken in heart, and binds up their wounds.").
In times like these, it's important to not take matters into our own hands, but to trust God and His justice. Romans 12:19 WEB says, "Avenge not yourselves, beloved, but give place to God’s wrath. For it is written, ’Vengeance belongs to me; I will repay, says the Lord.’"
